Base saturation of the soil is a measure of the

proportion of soil bases to acids

Can a 5.9 earthquake be more damaging than a 7.5?

possibly, if there are more people living in the area

The difference between chemical & physical weathering of rock is that

chemical weathering results in new substances

The difference b/w weathering & erosion is that

weathering is the breakdown of rock, erosion is the removal

The crustal abundance of 4 elements, makes up greater than 88% of the earth's crust, they are

oxygen, silicon, aluminum, iron

When surface area of a rock is increased

rock weathers faster b/c greater surface = more chemical act

The theory of plate tectonics states the following

the lithsphere is divided into plates, which move

Lichens are very important in

chemical weathering b/c they produce weak acids

an earthquake at the mid-Atlantic ridge
a huge eruption of lava from Mount St Helen's
ash from an Icelandic volcano
a volcano in the Phillipines
3
Base saturation of the soil is a measure of the
proportion of soil bases to acids
ability of water to drain
ability of nutrients to adhere to clay particles
particulate matter in lakes
4
The best agricultural soil is a mixture of
silt and clay
sand and clay
sand, silt and clay
sand, silt
5
At a hot spot
magma rises
plates are stationary
water rises
earthquakes are rare
6
Select the correct order of physical size of sediment particles from largest to smallest.
silt-sand-clay
loam-silt-sand
sand-silt-clay
loam-silt-clay
7
Can a 5.9 earthquake be more damaging than a 7.5?
possibly, if there are more people living in the area
possibly, because it's 1000 times stronger
never, because it's not strong enough
yes, because it causes a different kind of damage
8
Granitic rock is the dominant rock type in
at area where seafloor spreading is taking place
oceanic crust
continental crust
at subduction zones
9
Erosion is caused by
gravity
water
wind
all of these
10
The difference between chemical & physical weathering of rock is that
physical erosion results in erosion
chemical weathering results in erosion
physical weathering creates new substances
chemical weathering results in new substances
11
These things determine the properties of soils
time
topography
climate
all of these

B horizon
A horizon
O horzon
13
Topsoil is the
Both B & C horizon
A horizon
B horizon
C horizon
14
Erosion of soil can be accelerated by which of the following practices?
construction
all of these
road building
logging
15
The difference b/w weathering & erosion is that
erosion is the breaksown of rock, weathering is the removal
weathering is the breakdown of rock, erosion is the removal
weathering is a chemical process, erosion is physical
there is no difference b/w the two
16

20
The lithosphere includes
all of the crust
the entire mantle
part of the core
all of these
21
When surface area of a rock is increased
the weathers less rapidly b/c fewer surfaces are exposed
rock weathers faster b/c greater surface = more chemical act
the rock is less vulnerable to chemical weathering
the rock is less vulnerable to physical weathering
22
